    This seemed like a nice little washer until not long outside of the warranty the pump essentially blew apart. I spoke to Simpson customer service and they essentially said i was SOL. Because of the nature of the failure they said I could take it to a service center to have it inspected as being a manufacturers defect or not, then it would be sent to a separate claim office where they would do their own review to determine whether they would pay for the repair. This is not my personal washer, it was purchased for the company I work for, and now we are down a washer. I really don’t have the time to wait on their multiple stage forensic investigation into what is clearly a manufacturing issue. The metal on the pump casing is just junk. I need a well running pump now and in the future, so I will not risk buying another Simpson pressure washer if they will not step up and take care of this type of situation. I explained this to customer service, and that they could potentially be losing a big/long term customer as we are a growing company, but like most companies seem to operate nowadays they told me there was nothing they could do aside from sending my washer (which I will go ahead and fix myself) out on the road for an undetermined length of time and outcome. Buy at your own risk.Read more

    This is a review of the Simpson model MSH3125-S with the Honda GC190 engine. The short of it is the unit’s easy to setup and use, starts easy (really, it’s just one pull) and has great cleaning power. The container of engine oil provided with the unit is just the right size, pour it all in the crank case, add gas to the large fuel tank and you’re ready to go. The Honda engine has tons for power and the unit is a blast (pun intended) to use. I’ve already used it to clean my patio, the eaves and house siding. I also purchased a soap lance to use while washing my cars which worked great. My wife was a bit skeptical when I told her I was buying a power washer but after seeing the result with the patio and eaves she’s sold. Definitely 5 stars, if you want to know why read on… I shopped around beforehand and looked a multiple brands, size units and features before deciding on this model. Boy, am I glad I did. If you plan to do any heavy cleaning of decks or prepping a house for painting stay away from the electric units or lower (2000) PSI gas units, you’ll want the 3000+ PSI this size engine puts out. I would also like to note that I read the reviews for this unit and saw a lot of complaints about poor customer service. I figured I’d take the chance since I was purchasing through Amazon and if there was a problem with the unit when received Amazon is good about accepting returns. When I received my washer the plastic spray wand was broken. The unit had shifted in the box and the front bumper on the unit pushed against the wand cracking it and breaking a chunk out of the handle. I called Simpsons customer service the next day and a nice lady took my name and confirmed the model and serial number on my unit and then shipped me a replacement spray wand. The whole ordeal took about 5 minutes, done. While trying to decide on a power washer I went to two of the big chain hardware stores and looked at power washers they had on hand. I was looking at the craftsmanship, features and materials the various units were made from. 1) One of the first things that attracted me to this unit was the Honda engine. Honda is well known for their small engine reliability. I love Honda engines; my car, motorcycle, lawn mower are all Honda. 2) All the other high PSI units costing about the same as this unit had plastic bumpers and plastic hose and spray wand mounts. They were pretty colors and looked nice but almost all the display models had their plastic spray wand mounts broken off. Obviously no plastic parts was top of my list. This Simpson unit is all heavy gauge metal that will hold up to abuse. 3) The units with vertical crank shaft engines had the water pump mounted underneath. This made the units taller, less stable, and made it difficult to reach down and connect hoses. This Simpson unit has a horizontal engine shaft with the pump mounted in the rear where it’s easy to get at. 4) Another big plus is that the metal frame on this unit completely surrounds the engine and pump housing protecting them from accidental damage. Units with the pumps on the bottom are susceptible to being damaged when pulling them up stairs or across rough terrain. 5) One unit I looked at had the muffler mounted next to the hose storage and water pump. There were numerous complaints in the review section about melted hoses. This Simpson unit has the hose storage and pump in the back and the muffler up front. The muffler also has a head shield around it. Definitely no problem there. 6) The majority of units I saw had aluminum pump heads. This unit, like the larger more expensive units, has a brass pump head which will hold up much better than the aluminum units. A harder metal means no soft threads to strip and brass, unlike aluminum does not oxidize.Read more

    I thought I should post a review to offset some of the out-of-date information I read in the reviews that made me hesitate to buy the MSH3125-S. Fortunately, none of them turned out to be true for the version of the machine that’s currently shipping. I’ve had the MSH3125-S long enough to put about five hours on it, and I’ve used it on wood decking, stone walkways, painted steel, painted wood siding, painted steel siding, plastic window trim, and concrete. One of the reasons I picked it was because it has 10″ pneumatic tires, and my property is “challenging” for anything less. Although they might be fine on a nice, paved driveway or regular urban or suburban property, the brands with solid plastic tires and lightweight frames wouldn’t last long here. The frame the Simpson is built on looks very sturdy, balances the Honda engine very well, and is very easy to pull across difficult terrain, including gravel drives, uneven stepping stones, and dirt paths. It has a solid, 5/8″ axle that will make replacing the wheels/tires easy when the time comes. I read that some users felt the handle is too low; I didn’t find that to be a problem, but instead of pushing the machine, I walk beside it and pull it along with one hand. That works much better. The handle is at the right height and the tires manage the bumps and ridges much better than if I were to try to push it. Simpson seems to have solved the problem with the spray nozzles vibrating out of the holder on the machine. That hasn’t happened to me. Draining the oil isn’t a problem if you use the correct drain plug. The important thing to realize is that there are two drain plugs on the Honda GC190, one on the same side as the oil fill (don’t use that one!), and one on the opposite side on the fuel tank- and air cleaner-side of the engine. It’s the latter that Simpson intends for you to use, and they’ve provided a cut-out in the mounting plate to drain the oil into a pan placed beneath the machine. You can make oil changes even more convenient. I recommend getting aDrainzit HON1012 12mm Oil Changing Aid for Honda GX240, GX270, GX340, GX390, GC160 (it also fits the GC 190) to replace the drain plug before you add the oil to the engine the first time. You can route the hose inside the frame (see photo) and drain the oil right into a container placed in front of the machine. I found myself using the 15-degree spray nozzle–which most of the other brands of pressure washer I considered don’t include–more than any other size. It was the best size to clean the moss off my stone walkway and concrete. The 25-degree wasn’t powerful enough, and the 0-degree was too powerful and too narrow to be fast. I didn’t find the lack of a detergent tank to be a drawback, but a plus. For one thing, most detergent tanks are too small to really be much help. This pressure washer, like most, uses one gallon of detergent for every seven gallons of water. The detergent tanks on most pressure washers aren’t large enough to last very long. They also must be emptied at the end of the season and cleaned, which wastes some detergent, makes a mess, and is yet another maintenance job. With the MSH-3125-S, I can use a much larger container, or just use the container the detergent came in. However, the bottom line for me is that I don’t even need detergent. The MSH3125-S is powerful enough that it performed all the cleaning jobs I needed with water alone. The high-pressure hose the Simpson comes with appears to be very well-made and I didn’t have any problem with it kinking. I’m sure you could make it kink if you pulled hard enough on a loop (which you aren’t supposed to do with a high-pressure hose, anyway), but if you lay the hose out before you start work like you’re supposed to, it works very well. The slippery cover means it’s easy to pull behind you and easy to rinse off when you’re done. Another nice thing is that the Simpson comes already assembled. Other than the typical set-up tasks like oil, fuel, etc. pretty much all you need to do is turn the handle around and check the tires’ air pressure. Finally, I like the fact that the Simpson is compatible with a variety of aftermarket accessories, and that original parts for it are easily available here on Amazon and at your local big-box hardware store. If you need a sturdy, reliable, powerful pressure washer, especially if you live on a rural property, don’t hesitate to buy the Simpson MSH3125-S.Read more

    NO ISSUES WHATSOEVER! After reading countless bad reviews, I still went ahead and purchased this pressure washer. I was kind of expecting something bad to happen. Much to my surprise, it was a gem. Threw the oil in, hooked up the hose, voila….more pressure than most. No vibrating nozzles, no leaking oil, no hard starts….all good! I think Simpson has come a long way with this one and listened to the customer complaints. Even the shipping was good…no oil drenched box, no parts missing….NOTHING WRONG! Even my neighbour came over and asked what kind it was because he was so impressed with the pressure I was getting out of it. If you are like me and are hesitating because of the bad reviews from the past…don’t. This thing has tons of power and works like a charm. Dependable Honda engine to boot! I would highly recommend this pressure washer to anyone that needs this kind of power. My only complaint is the handle is a bit short…so if you are 6 foot something like me, you need to bend over while walking to haul it around. No biggie and I am sure I can rig something up to extend the handle.Read more

    Simpson has some confusing product numbers, this is actually MSH3125-S. It’s been updated with pneumatic wheels and an increased pressure to 3200psi from the last version. I went through three big box store machines in a week before buying this one, having found the others to be built like Chinese crap. This machine is amazing! Great engine, good pump, attached to a nice and simple frame which is solid. The gun and wand seem to be high quality, and the hose is nice as it will actually straighten out, unlike others. For the negatives….the handle rattled like crazy, sounding more like a bag of tin cans being dragged behind my truck. I solved this by wrapping some duct tape around the frame and installing the handle over it. Fixed. It’s also quite low to the ground for me, but whatever, it’s manageable, and might even be preferred by many for storage. Also, the wand is super short, 15”. I ordered a 31” extension for my Karcher 15” surface cleaner because my back is sore as I write this. All in all, an incredible, serious machine for the homeowner who uses these things a few times a year. Steer clear of the Chinese junk in your favourite box store and buy one of these. Trust me.Read more

    Do not whatever you do but anything from Simpson. Here’s a little story recap. I buy two for personal use, race track and home use. The first ones comes quickly and looks in good shape I start it and it pour gas out of the carb all over. I shut it down contact amazon and they ship another. It gets here and after using it 6/7 times it starts shutting off and I have now found out the head gasket is out of it. So now I’m stuck with two of these costing 500+ per unit and they both are junk do not buyRead more

    Bought this because it was pretty much the best for the money. Maintain it and it will last a very long time. Very powerful, light and easy to move, Honda engine. But damn is it loud. Need ear plugs when in use. Almost makes me regret not buying electric and dealing with breaking and replacing every 2 years. Lol. Update: 2 years of using and still going strong.Read more

    The pump started having problems after one season. It was kept empty and at room temperature. I had purchased the 2 year warranty which I was now in the coverage of and it took about 30 calls totaling 20 hours of being on hold and being talked down to. They made me e-mail them my receipt 3 different times claiming “they couldn’t find it”. Eventually I had been through their scripted prompts enough times that I was guiding there customer service providers to a faster call but, even still they would claim that another department wouldn’t let them proceed. I was hung up on about 8 times while on 20 minute plus holds. That all said if you feel like buying a pressure washer with a poorly made water pump and then have such an influx of cash that you would like to drop an extra $100+ to be on hold with a company that doesn’t seem to understand what they are doing then this is the washer and warranty for you! If you are lonely they will talk to you so, that’s a plus.Read more
